Baccarat

Two hands are dealt every round, called Player and Banker. Neither of them is yours. Your only job is to bet on which one you think will finish closer to nine, and you can back either one no matter where you're sitting.

Counting the cards. Cards count at face value. Aces count as one. Tens, jacks, queens and kings count as nothing at all.

Add the two cards together and throw away the tens digit. So a seven and an eight make fifteen, which counts as five. A nine and a four make thirteen, which counts as three. Nine is the best total there is.

The third card. Sometimes one of the hands takes a third card. There's a fixed set of rules deciding exactly when that happens, they're identical every single time, and the dealer applies them for you. Nobody at the table makes a decision about it.

How it ends. Whichever hand finishes closer to nine wins, and if you backed it, you're paid. You can also bet on the two hands tying, which pays well and doesn't come along often.

That's the entire game. There's no strategy to learn, no move to get wrong, and no way for a complete beginner to slow the table down. You pick a side, the cards turn over, and about fifteen seconds later you know how it went.
